New video clips have been added to the Mount St. Helens Web site, giving visitors a chance to take a virtual flight over the national volcanic monument.
The images were provided courtesy of Immersive Media of Portland, Ore., which shot the video under a special permit this past spring.
There are three video clips on the Mount St. Helens Teacher's Corner of the Gifford Pinchot National Forest Web site. They allow online visitors to take a 360-degree virtual flight around the Mount St. Helens blast zone, over the rim and into the crater of the volcano.
Mount St. Helens has had a Web presence since the late 1990s through a series of "volcano cams."
You can find the new videos and the webcams at www.fs.fed.us/gpnf/mshnvm .
Here is an online way to keep track of all the music stored on your computer.
1. Go to racksandtags.com. Create a free account and download the free software, which the Web site says is "ad-free, safe, secure, fast, small and fully automatic." The catalog you create can be public, shared only with friends or for your eyes only.
2. Run the software and direct it to the folders where your music is stored. The software scans your music files and transfers the information to your online catalog (including art if your files contain any), where your music collection can be viewed by album, artist or song.
3. Free accounts have a capacity limit of 1,000 albums. If your collection is larger than that, you can upgrade to a Pro account ($15 for one year or $25 lifetime), which provides unlimited album storage, advanced account customization and priority support.
